RE: Resolving close fields interference issues
I have been at Pete Waters when he was retuning radios from two clubs for the same reason. They had tried everything and the only solution was that one club used half of the frequencies and the other club used the second half. They took a pole of both clubs and allocated the frequencies that the majority at each club were using. Then my understanding was the club then paid to have the rest of the radios re-tuned. For about 60 members total I think he had a dozen or so that had to be re-tuned. Anyone purchasing a new radio was expected to confine their purchase to the agreed upon frequency allocations with no exceptions. Last I heard this was still working out with the two clubs.
